Image navigation system and method
First Claim
Patent Images
1. A method for processing image data comprising:
- comparing with a processor image data representative of a plurality of medical images, wherein the plurality of medical images represent spatially adjacent subject matter;
calculating with a processor a level of change of the image data from one image to the next in the plurality of medical images; and
presenting a viewer with the calculated levels of change of the image data for the plurality of medical images.

Abstract
A navigational tool is provided for selection of images of interest in large series of images. Difference indices are calculated between adjacent images in the series, and the indices are used to generate a navigational tool which can be presented as a graphical representation of differences between the images. A viewer may select specific locations or sets of images for viewing by manipulation of a virtual tool based upon the representation of the difference indices. The technique thus provides a highly efficient and intuitive tool for location of images in a series where particular features of interest or changes may occur, permitting rapid access and viewing of these images.

7. A method for diagnosing a patient, comprising:
-
acquiring a plurality of reconstructed images via a medical imaging system; comparing image data representative of the plurality of reconstructed images; and generating a scout navigation tool by quantifying a level of change of the image data from one reconstructed image to the next in the plurality of reconstructed images, the scout navigation tool including a graphical representation of progressive change between reconstructed images of the plurality of reconstructed images and a virtual tool for navigating though the plurality of reconstructed images based upon the level of change. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 27)

23. A system for processing image data comprising:
-
means for comparing image data representative of a plurality of images acquired via a medical diagnostic imaging system; and means for generating a scout navigation tool by quantifying a level of change of the image data from one image to the next in the plurality of images, the scout navigation tool including a graphical representation of progressive change between images of the plurality of images and a virtual tool for navigating though the plurality of images based upon the level of change, wherein quantifying a level of change of the image data includes quantifying change due to noise in the image data.
